BoostIO/BoostNote-Legacy ? reverse-engineered prompt

Build me a desktop note taking app for programmers that works on macOS, Windows, and Linux.

I want it to feel fast and simple, with a clean editor for writing notes and saving code snippets, plus an easy way to organize and find them later. Make it look modern, keep it offline first, and make the whole app feel polished like a real desktop app, not a website in a window.

If it helps, use the current docs online for any Electron or build setup details, and make sure it runs well on all three desktop platforms. I’d also like basic app features like creating, editing, deleting, and searching notes, with a nice sidebar or list for navigation.
